The SL-350QN is a 100m outdoor active infrared (AIR) beam set, wired which is designed for perimeter security. It can also be connected to an IP network when used in conjunction with our IP/POE module, the PIE-1.

A perfect alignment between transmitter and receiver is key to optimise the operation of the active beams. To make the optical alignment easier, the SL-350QN chassis features vivid yellow colours to be seen from the distance. Additionally, the "Sniper Viewfinder" is a new telescope lens which gives a high level of visibility for optical alignment work. Even over long distances, a perfect installation and stable performance can be achieved in a short period.

IP65 rated, the SL-350QN housing has been designed to resist against both water and dust. The two hoods featured on the front cover are positioned over the upper and lower beam to prevent frost from attaching to the cover and potentially affecting the signal power. The housing is made of UV resistant polycarbonate material to avoid deterioration caused by ultraviolet rays, whilst maintaining good transparency for the infrared beams over time.
